Just finished up doing the Z06 brake swap on my denali. they look good for sure, but they dont sound so good! applying the brakes at pretty much any pressure or speed they squeal like crazy. Ive pulled it apart twice now looking for the problem. Sanded down the pads ,re cleaned the rotors, made sure everything is aligned and tight, but nothing has worked. Any thoughts on what could be causing this?

I have 6 piston fronts and 4 piston rears.
15" baer rotors up front and 14's in the rear.
stoptech one piece pads all around.

Any help would be greatly appreciated! I just wanna drive it and enjoy how good the brakes are now without sounding like a freight train trying to stop!

 

What pad type are they?

 

Well I thought they were semi- metallic pads, but once you asked I checked to see what I actually ordered and I guess I bought "track day" pads by mistake haha. Im guessing that is the problem so I will have to order some new ones.
cant believe I missed that! oh well hopefully that is the fix.

 

Do they still squeal after getting some heat in them? If not, it's likely the pad compound.

 

did you bed in the brake pads?

 

Ive heard others mention this. What is it exactly?

 

The google.
